T all whom-it may"cm'zcern:

Be it known that 1, lnvixol. KREMER, a citizen of the United States, anda resident of the cityof New Yorlgboroughof Manhattan, in the county andState of New York, have invented a new and Improved Non ltefillableBottle, ofwhich the following is a full, clear, and exact description.

This invention relates to certain improvements in bottles, and moreparticularly to means whereby a bottle which has once been emptiedcannot be refilled.

The essential feature of the construction involves a valve having asubstantially. hemispherical seating portion and an oscillating portionextending therefrom, and so constructed that the last-mentionedportionmay be oscillated as the bottle is inclined, without moving thevalve from its seat until after the bottle has been inclined to apredetermined distance.

llelerenee is to be had to the accompanying drawings. forming a part ofthis specilication, in which similar characters of reference indicatecorresponding parts in both the figures, and in which Figure 1 is alongitudinal section through a bottle constructed in accordance with myinvention; and Fig. 2 is a perspective view of the bottle valve.

]n the specific form illustrated, the bottle neck is provided with aninwardly-directed llangc 1.1 supporting anoutwardlyextending ridge 12.The face of the flange together with the ridge, forms the valve seat,'and the ridge also serves to retain in position a spacing member 13hereinafter described. The valve includes asubstantiallyhemisphericalportion 14 and a conical oscillatory portion 15 preferably integraltherewith. The oscillatory portion is in the form of a truncated cone,the base of the cone fitting the llat surface of the hemisphericalportion and the outer end of the cone being provided with a recess 11').Above the. valve there is provided a plug 17 having a sinuous passage 18themrthrough, the curvature of the passage being such that the insertionof an instrument or wire. to unseat the valve is rendered dillicult, ifnot impossible. The plug rests against the outer end ofthc annularspacing men'iber 13 which limits inward movement, and the plug isprevented from withdrawal by a suitable locking means. lrel'erably, thislocking means includes two annular grooves, one in the plug 17 and thePatented Dec. 1 7, 1907.

other in the neck of the fbottle, one of the.

groovesbeing adapted for the reception of. a series Of'SlllELll balls19, while the plug is being 'inserted, and the two grooves.cooperatingwith the balls to positively prevent the plug from being withdrawn afterthe two grooves are brought into registry. This form of locking means isold and well-known in the art, and as it forms no part of the presentinvention, it is evident that other locking means may, if desired, beemployed in place thereof. The plug 17 carries a downwardl extendingprojection 20 adapted to enter the recess 16 of the valve, but normallyout of engagement with .the valve proper. The projection is somewhatless in cross section than is the recess, and the projection does notextend tothe bottom thereof. The projection as illustrated, is integralwith the 'plug 17, but it is evident that it may be carried by aseparate member if desired.

In the operation of the device the bottle is filled before the valve andplug are inserted. The valve is then dropped upon its seat and the plugcarrying the balls 19 is inserted. until the balls enter the annulargroove in the bottle neck. Upon inverting the bottle, the valve leavesits seat and drops into engagement with the projection 20, thuspermitting the liquid to freely flow from the bottle.

'The center of gravity of the valve is very low, and, therefore, as thevalve is being inclined it may move upon its seat to bring one edge ofthe recess into engagement with the projection 20. Thus the valve is notopened until after the bottle has been inclined to such an extent as tobring the center of gravity to one side of the valve seat.' Whicheverdirection the bottle is inclined, the valve will endeavor to rightitself until the edge of the recess engages with the projection and thusdelays the, time of opening of the valve to a considerable extent. Anyattempt to insert a liquid under pressure into the bottle wouldimmediately force the valve to its seat and close the opening.

Having thus described my invention, I claim as new and desire to secureby Letters Patent:

1.. In a non-refillable bottle, the combination of a bottle neckpresenting an annular valve seat, a valve seated thereon and having 2.In a non-refillable bottle, the combination of a bottle neckpresentingan annular valve seat, a valve seated thereon and having a hemisphericalbody and an upwardly-extending substantially conical oscillatory portionrigid therewith, and means engaging with said conical portion adjacentits outer end for limiting the oscillations thereof.

3. In a non-refillable bottle, the combina' tion of a bottle neckpresenting an annular valve seat, a valve seated thereon and comprisinga hemispherical seating portion and an oscillating portion substantiallyconical in cess but normally out of engagement with the sides thereof.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses,

IRVING I. KREMER.
